Failure to use adaptiveThreshold: CV_8UC1 in function adaptiveThreshold

Question

I have used openCV python and encountered an error.

img_blur = cv2.medianBlur(self.cropped_img,5)
img_thresh_Gaussian = cv2.adaptiveThreshold(img_blur, 255,          


        

Answer 1

you can change the code to slightly like this :

img_blur = cv2.medianBlur(self.cropped_img,5).astype('uint8')
img_thresh_Gaussian = cv2.adaptiveThreshold(img_blur, 255, cv2.ADAPTIVE_THRESH_GAUSSIAN_C, cv2.THRESH_BINARY, 11, 2)

just by adding ('uint8') while blurring has resolved my issue.
